Talking to some people at the club field, we were wondering who got this going. Who were the actual people that thought it up, and designed it ? We remembered the very first ad for the Spektrum transmitter and receiver for park flyers, around 2003 ? Anyway, those people really had a huge impact on our hobby. Does anyone know the history behind it ?

The answer might surprise you!

Here is a link:

https://www.google.com/#q=hedy+lama...read%20spectrum

The famous actress Hedy Lamarr, WWII era, was one of the key inventors and patent holders of Frequency Hopping Spread Spectrum, FHSS, communications. She was also a brilliant mathematician. She had contracts from the US Navy to further develop the technology in the 1940s!

Re our hobby, much credit goes to Paul Beard, the inventor of the Spektrum RC systems. I tested some early components for him.

2.4
I think he works for Horzion and Spread Spectrum is a trade mark of Bacham trains. Bobby

That's amazing about Hedy Lamarr. I had no idea.

Every time I hear her name, though, all I can think of is Harvey Korman in Blazing Saddles. "It's Hedley!!!"

Blazing Saddles - one of my favorite movies! Just watching Korman makes me laugh! Great cast of characters. "My name is Jim, but my friends call me....Jim!"

Wasn't it Jim Drew (XPS) the first to have 2.4 RC systems on the market ?

Been there, done that and old enough to know better.....

When I worked at Futaba in the early 90's we were playing around with prototype spread spectrum radios.

ROTFLMAO. No. Spektrum was out well before XPS.

Interesting Robert. What were the reasons for not moving ahead with it?

I always heard that futaba had 2.4 technology on remote cranes in Industry, and just adapted it to RC.

True, Futaba was using 2.4 technology 15 years before it was introduced in RC in the industrial marketplace.

From another forum....
XPS had the first FULL RANGE 2.4GHz RF available. Spektrum had the DX6, which was a park flyer only radio. Spektrum also had low power modules for R/C cars. We introduced the first aircraft modules, and the were also the first full range system available.

Been there, done that and old enough to know better.....

Juan,
You have to remember that Mr. Jim Drew is extremely full of himself and rewrites history at will. He also claimed his system had zero latency, a 100% spherical antenna pattern, and that an asynchronous system doesn't miss or repeat frames from the host system. All of which is completely false.

Understood....
All I can tell you is that I've been using the XPS system since the beginning..... all without a hitch.....unlike other systems out there. If his transmitter ever comes to market, I'll be there to try one out.... I'm currently using a JR 9303 transmitter with the XPS module and several receivers of different configurations and all have worked flawlessly.... if the transmitter never materializes, so be it. I'll still be happy with what I have....

Been there, done that and old enough to know better.....

Does the XPS system still exist? I remember reading about many, many problems with it back in 2007-2008.
